WVILLARD H. FULLER, OF PASSAIC, NElV JERSEY, ASSIGNOR TO THE SCOVILL &ADAMS COMPANY, OF NEW YORK, N. Y.

ROLL-HOLDER.

SPECIFICATION forming part of Letters Patent No. 439,651, dated November4, 1890. Application filed May 15, 1890. Serial No- 351,854. (No model.)

To all whom it may concern.-

Be it known that I, WVILLARD H. FULLER, of Passaic, in the county ofPassaic and State of New Jersey, have invented a certain new and usefulImprovement in Roller-Holders, of which the following is aspecification.

This improvement relates to the apparatus generally termedroller-holders, which consist of rollers and appurtenant parts acting incombination to successively expose different portions of a sensitizedfilm for photographing.

In the accompanying drawings, Figure l is a back view of a roller-holderembodying my improvement, the rear portion of the case being removed.Fig. 2 is a similar view of one end portion thereof without the rollers,which are normally arranged therein. Fig. 3 is a transverse sectiontaken at the plane of the dotted line x as, Fig. 1. Fig. 4 is a sectiontaken at the plane of the dotted line y y, Fig. 1, through the frontpart of a frame, which is included in the apparatus, and showing certainother parts.

Similar letters of reference designate corresponding parts in all thefigures.

A designates a frame consisting of two side pieces a a a front plate aconnected to said side pieces, and two cross-bars a a connected to therear of the side pieces.

13 designates a roller mounted in said frame and having wound upon it aphotographic sheet or film O. This roller has cavities in its ends whichengage with journals B B which are supported in the side pieces of theframe. The journal B is removable, and is made in the form of a screwand engages with that one of the side frames in which it fits. Hence itmay be at any time withdrawn for the purpose of removing the roller Band replacing it by another like it. The journal B and that end of theroller which receives the same are constructed to interlock, and as thisj ournal is provided with a flange b, which coacts with a friction-brakeN, a resistance is offered by this journal to the rotation of saidroller B. Owing to this a tension is produced on the sheet or film inits passage through the frame, and it is caused to lie flat.

D designates a roller journaled in the side pieces of the frame near tothe roller B.

E designates a roller journaled to the side pieces of the frame and nearthe other end thereof. The sheet or film passes from the forward side ofthe roller B to and around the rear side of the roller D, thence aroundthe front plate a and from the latter to the forward side of the rollerE. hen inserted in the apparatus, the end of the sheet or film isfastened to this roller E, so that by rotating this roller the sheet orfilm may be drawn across the front plate of the frame from end to end.The roller E is detachably mounted in the frame, so that when the sheetor film, after exposure, shall have been completely wound thereon itwill be possible to remove the roller. The roller is supported byjournals E E the latter of which is made in the form of a screw, so asto be adjustable longitudinally. The journal E interlocks with theroller E, and is provided with a worm-wheel that engages with a worm F.By rotating the worm motion may be imparted to the roller, and theroller will always be held against rotation after adjustment.

I do not here claim any of the parts which I have thus far described.The improvement for which I here seek protection resides in the meansemployed for marking the sheet or film.

G designates a swinging rod. It is provided with a number of pinpoints gand secured at the ends to arms g g which at the inner ends are fastenedto a rock-shaft 9 This rock shaft is j ournaled at the ends in the sidepieces of the frame, and may oscillate sufficiently to allow of forcingthe pins g through holes in the front plate a of the frame A to puncturethe sheet or film and afterward to withdraw said pins from beyond theforward surface of said front plate. 011 the roller D is a crank wristor pin d, which once in each rotation of go said roller comes in contactwith a projection g formed on the rear side of the arm g. Owing to theprojection g on the arm g the rod G is swung forward with a rapid motionand as quickly released. lVhenever the arm g is released by the passageof the crank wrist or pin beyond the projection g a spring G forces thebar rearward. This spring consists of a strip fastened at one end to therear side of the front plate a and is so bent that at the other end itwill impinge against the forward side of the rod G and operate to forcethe latter rearward. The crank wrist or. pin

d is set at such distance from the center of the roller D that thedistance between the two rows or sets of punctures 9 will be about thelength of the front plate a of the frame A, and consequentlysufficiently large for a picture.

This mechanism for puncturing or marking is very desirable, because itis not at all aflect-ed by the increase in the size of the sheet or filmWound upon any roller. Owing to this the crank wrist or pin mightobviously be placed upon the roller B, if preferred. If this were done,the roller D could be dispensed with and the roller B located in theposition which the roller D is shown as occupying.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a roller-holder, the combination, with rolls upon which a film ismoved, of an outwardly-moving rod having markers, an arm or arms on saidrod constructed to contact 3. In a roller-holder, the combination ofarod G, arms g 9 a crank wrist or pin operating on one of said arms tomove the said rod outwardly, and a spring for moving the rod inwardly,substantially as specified- 4. In a roller-holder, the combination of arod G, arms g g one of which is provided with a rearward projection, acrank wrist or pin operating on one of said arms to move the rodoutwardly, and a spring for moving the rod inwardly, substantially asspecified.
